The fog ransomware group claims a breach of Kombinat

The threat actor known as fog has listed Kombinat on their leak site, claiming to have obtained Gitlab source code. This announcement, which was published on the group's platform on February 4, 2025, follows an earlier claim made by the group regarding the attack date.

Ransomware groups often utilize leak sites as a primary tool in a strategy known as double extortion. In these scenarios, attackers do not merely encrypt an organization's data to disrupt operations; they also steal sensitive information to use as leverage. By threatening to release stolen data publicly, the threat actors aim to exert maximum pressure on the victim to fulfill ransom demands. This tactic shifts the focus from simple operational disruption to significant reputational and legal risks for the targeted entity.

Details of the alleged data leak

According to the announcement published by the fog group, the incident is linked to an attack that allegedly occurred on January 30, 2025. The group claims that the organization's Gitlab source code has been exposed. To facilitate the distribution of this information, the group indicates that these files are being shared via a torrent link.

While specific details regarding the total file count or the exact ransom demand have not been provided by the group, a screenshot associated with the announcement suggests that the leaked data is approximately 1 GB in size. Information regarding the specific identity and background of the fog group remains limited.

About Kombinat

Kombinat is a Vienna-based software development and technology consultancy firm. The organization focuses primarily on open-source projects, web development, and digital infrastructure solutions.

Potential implications and organizational risks

This alleged leak may pose significant risks to the organization's intellectual property and trade secrets. The exposure of source code is particularly sensitive, as it could lead to the identification of vulnerabilities within the organization's software infrastructure. Such exposure potentially facilitates secondary attacks, where malicious actors exploit discovered flaws to gain further access or disrupt services.

Furthermore, because the organization is based in Austria, the incident may trigger legal proceedings regarding data protection obligations under the General Data Protection Regulation (GDPR). Beyond legal and regulatory consequences, the publication of such data could result in substantial reputational damage among the organization's clients and business partners.

In such instances, organizations typically focus on incident response and forensic investigations to determine the scope of the breach. Common defensive steps for organizations facing such threats include implementing robust access controls, conducting regular security audits of source code repositories, and ensuring comprehensive monitoring of network traffic to detect unauthorized data exfiltration. The current assessment suggests that the threat actor may be utilizing this method of data publication specifically to exert pressure on the organization.
